The input torque on the shaft is 5 pound-feet and the output torque is 10 pound-feet. what’s the torque ratio? a. 4: 1 b. 1: 1 c. 3: 1 d. 2: 1

D. 2:1

Explanation:

The torque ratio expresses the ratio of the output torque to the input torque.

Given : Input torque= 5 pound - feet

Output torque : 10 pound-feet

Torque ratio is given by :-

Putting in the values we get:

Torque ratio=

Thus the torque ratio is 2: 1

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
